Senate committee substitute amends the 1st edition as follows.

Makes organizational changes regarding the proposed changes to GS 20-11, separating the proposed changes to subsections (c) and (d). Makes clarifying changes regarding the effective date of the act.

No longer eliminates the requirement of passing a road test from the limited provisional drivers license requirements for persons at least 16 but less than 18 years old, set out in GS 20-11(d). Instead, requires passing a road test administered by the Division or Motor Vehicles (DMV) or by a commercial driver training school certified by the DMV to administer road tests (currently, only DMV administered road tests are permitted).

Deletes the previous provisions mandating the DMV to use third-party vendors to administer the road tests. Instead, authorizes the DMV to certify commercial driver training school (training schools) licensed under Article 14 to administer road tests required by Article 2 of GS Chapter 20. Requires the DMV to oversee road tests administered by training schools. Requires documentation of passing applicants to be submitted to the DMV as the DMV specifies prior to license issuance. Directs the DMV to report to the specified NCGA committee by November 1, 2021, including the number of training schools certified, the change in the number of available road tests and the change in the number of days an applicant must wait to take a road test, and the effect on DMV customer service, or if no training schools are certified by November 1, 2021, the reasons for not implementing the provisions, and all measures taken and their effect to reduce wait times and improve customer service for road tests. 

Makes conforming changes to the act's long title.
